H 5 32	21 And = alp And = Alpheratz
	AB: H V 32. STFB 15. A is spectroscopic binary, P = 96.7d.
	AB: Optical pair, based on study of relative motion of the
	components using the method of apparent motion parameters.	Kiy2008
MKT 11	Aa,Ab: Separations and magnitude differences derived by model fitting
	to calibrated squared visibilities, using measurements with the Mark
	III interferometer. Spectroscopic and photometric data are combined
	with astrometry from the Mark III interferometer to derive orbital
	elements for the SB1 by Pan et al.	MkT1992a
	Pourbaix gives combined solution for this resolved SB2, yielding
	orbital parallaxes and component masses.	Pbx2000b
	Hipparcos astrometric solution adopted some elements from the orbit of	HIP1997d
	Pan et al. (1992).	MkT1992a
	Aa,Ab: Orbit determined by fitting revised Hipparcos intermediate
	astrometric data. Derived component masses are 4.05 +/- 0.50 and
	1.71 +/- 0.20 Msun.	Ren2010
	Aa,Ab: Malkov et al. (2012) derive dynamical, photometric, and
	spectroscopic masses 5.19 +/- 0.18, 4.10, and 3.09 Msun, respectively.	Mlk2012
	Aa,Ab: Docobo et al. (2014) use the spectroscopic elements of Pourbaix
	(2000), together with speckle data and the Hipparcos parallax, to	Pbx2000b
	derive the remaining orbital elements. The resulting masses are
	3.84 +/- 0.29 and 1.63 +/- 0.26 Msun.	Doc2014h
